Storage medium recording method and storage medium having multiple recording areas

Abstract

A storage medium includes a first area configured to have data stored therein in a first recording format; a second area configured to have data stored therein in a second recording format; a management table configured to manage a replacement area for a defect area in a data area in the storage medium, the management table being stored in the second area; an alert track stored in the first area; and a management data configured to manage the managing table and the alert track, the management data stored in the first area, wherein an end position of the first area is set a predetermined distance apart from a start position of the second area.

1. A storage medium comprising:
 a first recordable area configured to record data therein in a first recording format; 
 a second recordable area configured to record data therein in a second recording format; 
 a management table configured to manage a replacement area for a defect area in a data area in said storage medium, said management table being stored in said second recordable area; 
 an alert track stored in said first recordable area; and 
 a management data configured to manage said management table and said alert track, said management data stored in said first recordable area, wherein 
 a clearance area is set between an end position of said first recordable area and a start position of said second recordable area. 
 
   
   
     2. A storage medium according to  claim 1 , wherein:
 said alert track includes alert information for warning that the data stored in said second recordable area cannot be reproduced. 
 
   
   
     3. A storage medium according to  claim 1 , wherein:
 said first recording format includes Eight-to-Fourteen Modulation (EFM) modulated data, and said second recording format includes 1-7 pp modulated data. 
 
   
   
     4. A storage medium recording method comprising the steps of:
 recording first management data in a first recording format configured to manage a management table, said management table configured to manage in a data area of a storage medium a replacement area for a defect area in said data area; 
 recording an alert track managed by said first management data to said storage medium in said first recording format; 
 recording said management table at a position on said storage medium a predetermined distance apart from said alert track in a second recording format; and 
 recording second management data in said second recording format configured to manage data in said data area, 
 wherein said first management data and said alert track are recorded in a first recordable area and said management table and said second management data are recorded in a second recordable area. 
 
   
   
     5. A storage medium recording method according to  claim 4 , wherein:
 said alert track includes alert information for warning that the data stored in said second area cannot be reproduced. 
 
   
   
     6. A storage medium recording method according to  claim 4 , wherein:
 said first recording format includes Eight-to-Fourteen Modulation (EFM)modulated data; and 
 said second recording format includes 1-7 pp modulated data.
